Abstract: A computerized voting system has a central computer, regional computers and voting modules connected to a data transfer link for communication with one another. The voting modules access the central computer database under control of the central computer control center. Voter data is created at one of the voting modules and communicated to the database for storage. Input voter data for a given voter at any one of the plurality of voting modules during an election is compared to the stored data for the given voter to verify that the given voter is eligible to vote. Access to the stored voter data for the given voter during an election is restricted to prevent the given voter from voting more than once during the election.
